# Engineering Skills — Codex CLI Instructions

When working on engineering tasks, use the engineering skill system:

## Routing

1. **Identify the domain:** Architecture, frontend, backend, DevOps, security, AI/ML, data, or QA
2. **Read the specialist SKILL.md** for detailed instructions
3. **Use Python tools** for scaffolding and analysis

## Python Tools

All scripts in `engineering-team/*/scripts/` are stdlib-only and CLI-first. Run them directly:

```bash
python3 engineering-team/senior-fullstack/scripts/project_scaffolder.py --help
python3 engineering-team/senior-security/scripts/threat_modeler.py --help
python3 engineering-team/senior-frontend/scripts/bundle_analyzer.py --help
```

## Key Skills by Task

| Task | Skill |
|------|-------|
| System design | senior-architect |
| React/Next.js | senior-frontend |
| API design | senior-backend |
| Full project scaffold | senior-fullstack |
| Test generation | senior-qa |
| CI/CD pipelines | senior-devops |
| Threat modeling | senior-security |
| AWS architecture | aws-solution-architect |
| Code review | code-reviewer |
| E2E testing | playwright-pro |
| Stripe payments | stripe-integration-expert |

## Rules

- Load only 1-2 skills per request — don't bulk-load
- Use Python tools for analysis and scaffolding
